To all 'whom t may/concern.'

Be it known that I, FRANK REESE, a citi-l vzen of the United States, residingat Minneaplis, in the county of Hennepin and .State of Mmnesota, have invented certain new and useful' Improvements in Portable Grrooving-Tools;- and I do hereby declare the following to be a full, clear, and exact descri tion -of the invention, such as will enabe othersskilledin theart to which it appertains to make and use the same.

My invention has f or its objectprovide an. extremely simple and highly eicient portable lgroovingtool; and to such ends, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined `in the.

` claims.

A tool of the above character may be advantageously. used a -greatmany different places and for a great 'many different kinds of work where'grooves are required, but'is especially adaptedforuse in cutting grooves `someparts' belng broken away and' some in built-up or permanentwooden structures where thepart lto be groovediseltherfixed or, cannot be conveniently presented t0 a xed grooving machine. For example, the

tool is very serviceable for use in cutting .grooves in the edges of sash, as preparatory for .the-.application yof the metallic weatherv stripswhich have projecting flanges :to work in the grooves.

' In the accompanyingdrawings which' illustrate the invention in its preflerred form, like :characters indicate like parts throughout the several views. 5

Referring to the drawings:

As a motor for propelling the grooving tool or cutter, I employ a comparatively small electricmotor indicated, as an entirety, by the numeral L1. .The armature shaft 5`of this motor projects at one side of the casing, and to the Vprojecting end thereof, a groov- -iiig tool in the form of a small circular saw 6. is detachably secured by suitable means,

*such as a nut 7 This grooving tool 6 works within a housing 8 that is pivotally attached spec-mention of Letters Patent. Application med July 17, 191e. serial No. ioaeei.

to a boss 9 on the motor casing and is adj ust' ably connected 'to a similar boss 9a on said casing, by a clamping screw 10 that works in a slot 10a formed in an extended flange of said housingS. The said housing 8 is pro-y vided with a flat bottom or runner plate 11 having an opening through'which the lower portion ofthe sawor cutting tool 6 works withclearance. To assist the screw 10 in positively holding the housing in its dif- 'ferent vertically adjusted positions on the pivot 9, a set screw 12 works through an ear 13-on the boss 9 and bears against the underlying end portion of the runner plate 11; i

The gage strip 14 is detachably secured tov the inner edge of the under surface of the `runner plate 11, byv screws 14a. Tomake the said gage strip 111 adjustabletoward and from the lower edge of the cutter 6, the screws. 14a work through kslots 14;b in the` runner plate 11, as shown in Fig. 2, wherein the screws 14a are sectioned so as to expose the said slots. The bottom of the housing 8`is open so that the lower portion of the groovlng tool projects vmore or less below the same. At its rear, the said housing 8 is formed with tangentially and laterally extended discharge spout 15 for the saw dust or chips cut by the tool 6.

On itsfront face, the lhousing 8 is pro- .vided with a detachable plate 8il shown as held thereto by screws 16, and which plate, when removed, aords access to the grooving tool or cutter and permits the same to be removed and another of different size or character substituted therefor.

The back or inner plate of the housing 8, is formed with a slot 17, which clears the tool or s aw6 will cut will depend upon the projection thereof, below the bottom of the so-called runner plate 11, and this projection may, as is obvious, bevared by adjust- Y sawfor-cutter and onjepposite sides of the motor" the tool may be easily. sta ed and L guide 1and-held to its The saw dust or chips-will,'byf*centrifugal 1forcefbe thrown voutjthrough the discharge g spout-1 5., .If.desi`red,y 'a tool yfor'v carrying the Asame to (a 4'suitable receptacle mightbe provided.
